- 2006 Limited V8
So I think this is turning my love affair with my 2006 V8 Limited into a nightmare. Just don't want it to be a breakup
In mid August, I began driving EXTREMELY short distances. About a month later, my car would shake and idle extremely rough after warmed up. Laggy acceleration, "jumping" engine at idle etc. Finally, my CEL came on and pointed to a misfire on the 8th cylinder. I was going to do process of elimination by switching the coil on the 8th with the 7th cylinder but noticed the coil had rust and was "wet", (odorless). A week or two later, no CEL but same symptoms so I bought a new coil and threw it in the 7th, (contained that rusted one). Perfect. All was well in the world. BUT I did notice something: When I stomped the gas, there was a buck / stutter. So long as I kept it in gradual city driving, it was cool. I just figured I'd have to go out on the freeway and open it up for all that short driving I had been doing. I decided it'd be best to throw in some Techron fuel cleaner and run Seafoam. Check. Filled it up with quality gas, had to change the brakes, and Boom - battery died.
Anyway, I bought a new battery and, since it was unhooked, decided today would be a good day to clean the throttle and MAF. Did both and reinstalled the battery. Let it "relearn" the idle and marveled at what a great job I did - considering I'm not very hands on. Then...I hit the freeway....

Everything was going fine until I was going up a hill. When I tried accelerating from 55mph to approximately 57/58mph, it did that stuttering again. Symptoms immediately disappeared when I continued at 55mph. Each time I tried going to 60, same thing and each time I released to 55, all good. As I was going down the hill, I noticed I could push past 60 with less stutter that all but disappeared - until another hill forced me into the same issue. This time, my CEL began flashing!!!!! I freaked out and drove to the end of the expressway where it meets with side road. Car was shaking BAD as I waited at the light but noticeably better when I sat in Neutral. (Flashing CEL went away by this point btw). I turned onto the parallel road for my return trip and the car was fine. I mean fine. As I approached a light and anticipated shifting to Neutral again, I noticed all was right with the world. But two times on this road during my return, I'd punch the gas, get that stuttering, the CEL would flash, and eventually everything would work out.
As of now, the car made it back and purs beautifully - as if I made this up. But it's a matter of time and from what I read, a flashing CEL is a death-cry.
Any thoughts on what I should do? Unfortunately, funds are limited (very limited), as we're closing on a house. I switched the air filter today, but no clue about when the coils/plugs, or fuel filter were done. And I've heard that a lot of these symptoms sound like a misfire that could lead to the TPS. Should I wait for another CEL and remain off the highway?
